Philadelphia, Wilmington and Baltimore Railroad

Baltimore and Philadelphia Railroad. However, as a condition of the sale, no passenger service was provided. The line passed into Conrail in 1976 and SEPTA in 1983, with passenger service to the Philadelphia International Airport beginning on April 28, 1985.
Infill stations were planned from the beginning of service, two of which were on the Airport Line proper: one at 70th Street, the other one at 84th Street. The latter station was opened in 1997 as
Eastwick, while 70th Street was never built, and has since disappeared from maps. Additionally, University City station (proposed as "Civic Center", now
Penn Medicine Station) opened in April 1995 to serve all R1,
R2 and
R3 trains passing it. All these stations appeared on 1984 SEPTA informational maps, the first ones to show the Center City Commuter Connection and the Airport Line.
